Davinci Resolve playback lag

[Idkwhat2putheresowhatever]

When I add an effect such as a title into Davinci Resolve 15 and try to playback the video. The playback lags throughout the effect. Why is this so? I have already enabled CUDA but my graphics card doesn't seem to be doing anything and it's utilisation is at 5%. My video is 1080p30 if that helps. 

 

I have an Intel Core i7-8700, 16GB of 2666MHz RAM, GTX1070Ti and running off a WD Blue SSD

Seems odd... Are you by any chance using your iGPU for Resolve?(The GPU used can be changed in the settings)

I have similar problem, playback is smooth first few secs and then it slowdown unless i pause and play it back. I thought my proc simply showing it's age.

I have disabled my iGPU in my bios and Davinci resolve only recognises the 1070Ti as my GPU in preferences. I mean, surely a 6 core 12 thread i7 and a GTX1070Ti would be sufficient for editing.

Yeah, I think so, too... Are all of your drivers up-to-date?

Yep. Also went to check for driver updates on GeForce Experience. Everything is up to date.

It's the same on my system, 2700X and 1070Ti.
